AbstractGreen areas located on the peripheries of cities have the potential to become green public spaces not only of recreational but also educational character, promoting at the same time the knowledge about environmental protection. The cities included in the research belong to the małopolskie voivodeship (Lesser Poland voivodeship). With the use of geospatial data of land cover, as well as territorial forms of environmental protection, it was pointed that 48.4% of forest, wooded and shrub green areas located within city borders are covered by a form of environmental protection, thus being a valuable resource of significant nature potential. Making such spaces available in a conscious and attractive way is presented on the example of projects implemented in the cities of: Stary Sącz, Nowy Targ and Kraków. The presented projects were used to make recommendations for city authorities to create green public spaces.

Abstract Mediterranean regions have experienced significant soil degradation over the past decades. In this context, careful land observation using satellite data is crucial for understanding the long-term usage patterns of natural resources and facilitating their sustainable management to monitor and evaluate the potential degradation. Given the environmental and political interest on this problem, there is urgent need for a centralized repository and mechanism to share geospatial data, information and maps of land change. Geospatial data collecting is one of the most important task for many users because there are significant barriers in accessing and using data. This limit could be overcome by implementing a WebGIS through a combination of existing free and open source software for geographic information systems (FOSS4G). In this paper we preliminary discuss methods for collecting raster data in a geodatabase by processing open multi-temporal and multi-scale satellite data aimed at retrieving indicators for land degradation phenomenon (i.e. land cover/land use analysis, vegetation indices, trend analysis, etc.). Then we describe a methodology for designing a WebGIS framework in order to disseminate information through maps for territory monitoring. Basic WebGIS functions were extended with the help of POSTGIS database and OpenLayers libraries. Geoserver was customized to set up and enhance the website functions developing various advanced queries using PostgreSQL and innovative tools to carry out efficiently multi-layer overlay analysis. The end-product is a simple system that provides the opportunity not only to consult interactively but also download processed remote sensing data.

Cultural Role

One of the criteria for a comfortable ecologically clean urban environment is access to green spaces, their number and quality in any given city. Public green spaces play an important socio-cultural role in the context of active and passive recreation of citizens, various types of recreational activities. The relevance of this study is due to increased attention to the formation of open public spaces in the city of Krasnoyarsk. The purpose of this work is to trace the evolution and identify the social and cultural significance of the green public spaces in Krasnoyarsk. The objectives of the research are to study the green spaces of Krasnoyarsk in a historical retrospective, analyze the green spaces of Krasnoyarsk from the point of view of their ecological significance, recreational use. Research methods included literature review on the topic, analysis of historical data, field survey of the territory, long-term observation, photographic recording, comparative retrospective analysis, and graphic-analytical method. The study captures the most common types of public green spaces and their role in creating a comfortable urban environment. It traces in the most detail the evolution and cultural significance of the most important historical green spaces in Krasnoyarsk: the City Garden (now the Central Park), Yudinsky Garden, Krutovsky Garden. These examples show that gardens and parks can be formed both on the basis of the natural environment of urban forests, and artificially created by the efforts of citizens, that over time they can undergo various quantitative and qualitative, planning and functional transformations. Despite the transformations that have taken place, all the studied historical objects still exist and are used for their intended purpose. In addition to these historical green areas, we examine the newly organized public green spaces with a cultural and recreational component over the past decades: Tatyshev Park, All-season Fun-Park Bobrovy Log, Flora and Fauna Park Roev Ruchey, Dream Gardens and others. The article notes the importance of municipal, public and private initiatives in the organization of local green areas. The analysis allows us to assert that there is a certain system of public green spaces in Krasnoyarsk. It has disadvantages, such as an uneven distribution of green areas throughout the city, lack of interconnections between individual elements, aging of certain areas of greenery, and the complete destruction of some. Nevertheless, the city authorities, architects, designers and the general public make great effort to create a green framework for Krasnoyarsk destined to have an important recreational and cultural role.

Data Layers

Land cover change (LCC) is typically characterized by infrequent changes over space and time. Data-driven methods such as deep learning (DL) approaches have proven effective in many domains for predictive and classification tasks. When applied to geospatial data, sequential DL methods such as long short-term memory (LSTM) have yielded promising results in remote sensing and GIScience studies. However, the characteristics of geospatial datasets selected for use with these methods have demonstrated important implications on method performance. The number of data layers available, the rate of LCC, and inherent errors resulting from classification procedures are expected to influence model performance. Yet, it is unknown how these can affect compatibility with the LSTM method. As such, the main objective of this study is to explore the capacity of LSTM to forecast patterns that have emerged from LCC dynamics given varying temporal resolutions, persistent land cover classes, and auxiliary data layers pertaining to classification confidence. Stacked LSTM modeling approaches are applied to 17-year MODIS land cover datasets focused on the province of British Columbia, Canada. This geospatial data is reclassified to four major land cover (LC) classes during pre-processing procedures. The evaluation considers the dataset at variable temporal resolutions to demonstrate the significance of geospatial data characteristics on LSTM method performance in several scenarios. Results indicate that LSTM can be utilized for forecasting LCC patterns when there are few limitations on temporal intervals of the datasets provided. Likewise, this study demonstrates improved performance measures when there are classes that do not change. Furthermore, providing classification confidence data as ancillary input also demonstrated improved results when the number of timesteps or temporal resolution is limited. This study contributes to future applications of DL and LSTM methods for forecasting LCC.

Green spaces are playing an essential role for ecological balance and for human health in the city as well.They play a fundamental role in providing opportunities for relaxation and enjoying the beauty of naturefor the urban population. Therefore, it is important to produce detailed vegetation maps to assist plannersin designing strategies for the optimisation of urban ecosystem services and to provide a suitable planfor climate change adaptation in one fast growing city. Hence, this research is an investigation using 0.5m high-resolution multispectral Pléiades data integrated with GIS data and techniques to detect andevaluate the spatial distribution of vegetation cover in Erbil City. A supervised classification was usedto classify different land cover types, and a normalised difference vegetation index (NDVI) was usedto retrieve it for the city districts. Moreover, to evaluate the accessibility of green space based on theirdistance and size, a buffer zone criterion was used. The results indicate that the built-up land coverageis 69% and vegetation land cover is 14%. Regarding NDVI results, the spatial distribution of vegetationcover was various and, in general, the lowest NDVI values were found in the districts located in the citycentre. On the other hand, the spatial distribution of vegetation land cover regarding the city districts wasnon-equal and non-concentric. The newly built districts and the districts far from the Central BusinessDistrict (CBD) recorded the lowest vegetation cover compared with the older constructed districts.Furthermore, most of the districts have a lack of access to green spaces based on their distance and size.Distance and accessibility of green areas throughout the city are not equally distributed. The majority ofthe city districts have access to green areas within radius buffer of two kilometres, whereas the lowestaccessibility observed for those districts located in the northeast of the city in particular (Xanzad,Brayate, Setaqan and Raperin). Our study is one of the first investigations of decision-making supportof the spatial planning in a fast-growing city in Iraq and will have a utilitarian impact on developmentprocesses and local and regional planning for Erbil City in the future.

Housing Estates

The paper focuses on the phenomenon of intense, uncontrolled densification of large-panel housing estates in Poland. Despite the fact that such housing estates as a legacy of the Modernist concept of segregation of functions are often burdened with problems, they still have considerable potential, which results predominantly from their urban advantages, such as functional and spatial logic, large amounts of open public space, and abundance of greenery. Unfortunately, this potential is being destroyed by introducing new buildings, ignoring the existing urban layout of the housing estate along with its original compositional assumptions. This type of densification results from—without limitations—the pressure exerted by developers in the free-market economy, and it often leads to problems such as the devastation of urban layouts of these housing estates, breaking the continuity of public spaces, appropriation of green areas, strengthening of monofunctionality, etc. This problem is becoming noticeable in the scientific debate, although it is still difficult to obtain reliable data illustrating the densifications of such housing estates. The goal of this paper is to present the scales and character of such densifications of the large-panel housing estates, which pose a threat of devastation of their urban layouts often considered as urban heritage. The paper proposes a method of a quantitative analysis of the housing estates with reference to the increase in the built-up area and a qualitative analysis of the character of development with reference to its distribution. This method comprises a sequence of subsequent steps with relevant criteria. In the results, it demonstrates the scale of the problem, which in many cases is already big and still growing. The resultant threat of devastation of the urban layout and its consequences are presented upon selected examples of housing estates in Cracow, Poland. This paper is a voice in a discussion devoted to the current status, but most of all to the future of large-panel housing estates, particularly in terms of their protection as valuable achievements of urban planning of the second half of the 20th century, and to stopping unfavorable tendencies of urban destruction.

Urban parks should be inclusive for all. Availability and accessibility of urban parks determine the quality of life in cities. The importance of access increases for residents with limited mobility who, facing obstacles due to inadequate adjustment of the surrounding physical space, are exposed to social exclusion. Five groups of respondents completed a survey questionnaire revealing their attitudes towards green areas and indicating barriers to parks’ accessibility. The groups were designed to include blind and vision impaired people, those who use a wheelchair, have a physical disability of any kind, their carers/assistants and parents pushing strollers. The results revealed more similarities than differences among the five groups (the differences included preferences towards the neighbourhood and destination parks, physical barriers in parks, as well as using assistive technology devices and mobile assistive applications). Overall, city residents with mobility difficulties find those green public spaces as an important element of their life quality.

Urbanization is currently one of the most pressing environmental issues which cuts across all countries at unprecedented rates and intensities, with far reaching consequences on ecosystems, biodiversity and human wellbeing. This paper assessed urban expansion and land use/land cover changes in Sokoto metropolis, North-western Nigeria using Remote Sensing and GIS. Landsat images of 1990, 1999 and 2015 were processed for LULC classification and change detection using the Maximum Likelihood Classification, Post Classification Comparison techniques and the Land Change Modeler. The classification revealed five broad land cover classes which include Built-up Area, Farmland, Green Area, Open Space and Wetland/Water. The Built-up and Green areas continuously increased while Farmland and Open space decreased throughout the study period. The metropolis expanded radially at a faster rate between 1999 and 2015 with the highest rate of increase (1890.5ha per annum) recorded in the Built-up Area. This implies a doubling time of approximately 30 years at the expense of Farmland and Open space which may be completely exhausted in 40 and 29 years respectively. Infrastructural provision should thus align with the rate and direction of growth and where the Green Area is converted, replacement should be made to ensure continued supply and stability of the numerous ecosystem services green areas provide.

Community hygiene conditions and equipment represent significant indicators of the quality management of green areas. As a space of exceptional importance for protection of forest complex and biodiversity in an urban environment, Zvezdara forest is placed under protection as a natural monument by an act of the Assembly of the City of Belgrade, where measures of environmental protection and preservation of this area, as one of the most important green areas in this part of the city, are also defined (wind protection role, enrichment of the air with oxygen, thermoregulation, etc.), but as well as a space for sports, recreation, picnics. This research presents the community hygiene problems (?illegal landfills?, lack of garbage cans, hydrants, public toilets and drinking fountains, etc.) and environmental issues (?wild? construction, landslides, etc.). The aim of this research is the recommendations of environmental protection measures and removal of community hygiene and environmental issues, presented in the final part of this research paper, which could be used in the future during preparation of planning documents, in order to achieve better environmental management in the area of Zvezdara forest.
